Two spiro-OMeTAD analogues featuring a spiro[fluorene-9,9-xanthene] central core have been designed and applied in PSCs as dopant-free HTLs. The device based on SP-SMe reveals better performance operational stability than the spiro-OMeTAD-based device.
This study introduces a novel approach centered around the design and synthesis of an interfacial passivating layer in perovskite solar cells (PSCs). architectural innovation is realized through development specialized material, termed dithiafulvene end-capped Spiro[fluorene-9,9′-xanthene], denoted by acronym AF32. In this architecture, thoughtfully attached to spiroxanthene fluorene core with phenothiazine as spacer unit, possessing multiple alkyl chains. AF32 passivates defects...
For the first time, we present detailed synthesis, photophysical, electrochemical, host-guest and charge transport properties of spiro[fluorene-9,9'-xanthene] (SFX) carbazole macrocycle SPS-NR-02. The electron hole values measured using space limited current (SCLC) method resulted in ambipolar with an to mobility ratio 0.39.
